It's formed in magma before it is oozed up through the ocean floor at the Mid-Atlantic Ridge. While it is still liquid, the iron molecules in the lava can orient themselves along the magnetic lines of force that envelope the earth.

What causes the magnetic striping noticed about the mid ocean ridges?
These "stripes" formed the pattern known as magnetic striping. ... They hypothesized that the magnetic striping was produced from the generation of magma at mid-ocean ridges during alternating periods of normal and reversed magnetism by the magnetic reversals of the Earth's magnetic field.
Ocean ridges are formed by what boundaries?
Divergent boundaries form ocean ridges.
Marine magnetic anomaly belts run parallel to?
Mid-Ocean Ridges
What formed ocean crust?
Ocean crust is formed by intrusive magma at mid-ocean-ridges. The magma cools and solidifies into peridotite, basalt, or gabbro.
Mid-ocean ridges are actually underwater mountain ranges.?
It is true that mid-ocean ridges are underwater mountain ranges. These ridges are where the lithosphere is moving apart and new oceanic crust is being formed.

How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
Ocean ridges are formed by what boundaries?
Divergent boundaries form ocean ridges.
Where is the newest ocean crust formed?
mid ocean ridges
What are mid ocean ridges formed from?
the wind ;)
What are ocean ridges formed by?
Divergent boundaries
What properties of iron bearing minerals on the seafloor support the theory of seafloor spreading?
iron bearing minerals can record Earth's magnetic field direction. when Earth's magnetic field reverses, newly formed iron bearing minerals will record the magnetic reversal. magnetic reversals show new rock being formed at mid-ocean ridges. This helped explain how the crust could move
Ocean crust is formed where in the ocean?
New ocean crust is formed at mid-ocean ridges where tectonic plates are diverging (spreading apart).
The seafloor magnetic pattern is best described as?
parallel to and symmetric about ocean ridges
Marine magnetic anomaly belts run parallel to?
Mid-Ocean Ridges
Where are oceanic crust and lithosphere formed?
At the mid-ocean ridges.
Does theory continental drift state that new ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
